# Postmortem Writing

Write up the incident without putting anyone on trial

## What this does

Something broke, it is fixed now, and someone has to write it up so the team learns from it instead of relitigating it. This helps you produce a blameless account: what happened when, what actually caused it, and what to do about it. Reach for it after an incident, or when your incident reviews keep going nowhere.

### Top 3 things it does for you

- Write a blameless postmortem after an incident
- Build the timeline of what happened when
- Get to the root cause

## Questions

### Is Postmortem Writing safe to install?
